MS Access VBA Form Filter Example

In a previous post I gave an example of a MS Access form filter.

This revision is to demonstrate how to requery a form after the combobox changes, and not when a button is clicked.

Here is the code:

Private Sub cboDescription_AfterUpdate()
    
    Me.FilterOn = False
    m_Where = m_Where & " AND Description = '" & Me.cboDescription & "'"
    FilterThis
    
End Sub

Private Sub cboIncomeExpense_AfterUpdate()
    Me.FilterOn = False
    
    'clear the WHERE variable
    m_Where = vbNullString
    
    m_Where = m_Where & " AND [Income/Expense] = '" & Me.cboIncomeExpense & "'"
    FilterThis
End Sub
Private Sub chkTax_AfterUpdate()
    m_Where = m_Where & " AND [Taxable] = " & Me.chkTax
    FilterThis
End Sub

Sub FilterThis()
    
    'clean the string first
    If Left(m_Where, 4) = " AND" Then
        m_Where = Mid(m_Where, 5)
    End If
    
    Me.Filter = m_Where
    Me.FilterOn = True
    
End Sub

I also added a “search” box to query a table displayed in a lower form.

Here is the code:

Private m_Where As String

Private Sub btnReset_Click()
    Me.RecordSource = "Categories"
    
    Me.FilterOn = False
    
    'clear all the variables
    m_Where = ""
    Me.cboDescription = ""
    Me.cboIncomeExpense = ""
    Me.chkTax = 0
        
    
End Sub

Private Sub btnSearch_Click()
 'Search as you type
    
    Dim strSearch As String
    Dim strSQL As String


    strSQL = "SELECT * FROM Categories WHERE Description like """ & Me.txtSearch & "*" & """"

       
    Me.RecordSource = strSQL
    

End Sub

Let me know if I need to elaborate.
